Abstract

Liquid, especially water filters and the use thereof are disclosed. The filters, which may be constructed in a configuration which creates a maximum surface area, per unit volume, for filtration of the liquid are self-supporting structural elements which are comprised of a porous matrix having uniformly entrapped therewithin activated carbon particles. The porous plastic matrix preferably is formed from a thermoplastic polymeric material having an average particle size substantially in excess of the average particle size of the activated carbon particles.
